Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] As Figures 1-3 shown, a trenchless ultraviolet light curing repair device for pipelines includes a moving frame 1;

[0024] Symmetrically arranged horizontal sliding grooves 2 are provided on the outer side of the moving frame 1, and a curing component is arranged on the horizontal sliding grooves 2;

[0025] Among them, the curing component includes a support screw rod 3 slidably arranged inside the horizontal chute 2, a light source fixing seat 4 erected between the support screw rods 3, and the radius and length of the light source fixing seat 4 are both smaller than those of the moving frame 1. A plurality of groups of lamp holders 5 are arranged at intervals outside the light source fixing seat 4, ultraviolet lamps 6 are arranged on the lamp holders 5, and fastening nuts 7 are movably arranged at one end of the support screw rod 3 away from the light source fixing seat 4. The light source fixing seat 4 is slidably arranged in the moving frame 1 through the support screw rod 3, and the light source fixing seat 4 can be fixed by the fastening nut 7. When the fixing of the light source fixing seat 4 by the fastening nut 7 is released, the light source fixing seat 4 can move along the horizontal chute 2 through the support screw rod 3. Since the radius and length of the light source fixing seat 4 are both smaller than those of the moving frame 1, the staff can pull out the light source fixing seat 4 outward during use, so that the ultraviolet lamp 6 is exposed outside the moving frame 1, which is convenient for curing the inner lining of the pipeline. And because the radius of the light source fixing seat 4 is small, the distance between the ultraviolet lamp 6 and the pipe wall is relatively large during use, so that the irradiation area of the ultraviolet lamp 6 is large, further improving the curing effect of the device. When the device is not in use, the staff can slide the light source fixing seat 4 into the interior of the moving frame 1, which forms good protection for the light source fixing seat 4 through the moving frame 1, and also further reduces the occupied space of the device during placement, facilitating storage.

[0026] In this embodiment, specifically, two groups of symmetric telescopic sleeve rods 8 are slidably arranged inside the moving frame 1. The telescopic sleeve rods 8 are located behind the horizontal chute 2. Moving seats 9 are arranged at the mutually remote ends of the telescopic sleeve rods 8. The moving seats 9 are located outside the moving frame 1. Ball bearings 10 are rotatably arranged inside the moving seats 9. Bidirectional lead screws 11 are rotatably sleeved inside the mutually close ends of the telescopic sleeve rods 8. A stress part 12 is arranged in the middle area of the bidirectional lead screws 11. A guide rod 13 is arranged on one side of the moving seat 9. One end of the guide rod 13 penetrates through the moving frame 1, and a baffle is arranged at the penetrating end.

[0027] During the use of the device, the arranged bidirectional lead screws 11 can drive the moving seats 9 and the ball bearings 10 to move synchronously, so as to ensure that when the staff drives the bidirectional lead screws 11 to rotate through the stress part 12, the distances between the two ball bearings 10 and the center of the moving frame 1 are equal, enabling the device to be smoothly placed into pipelines with different diameters, ensuring the stable movement of the moving frame 1. During the movement of the moving seats 9, the arranged guide rod 13 can form guiding and limiting for it, preventing the moving seats 9 from deflecting and ensuring the stability of the moving seats 9 during adjustment.

[0028] In this embodiment, specifically, a reinforcing frame 14 is provided at the end of the moving frame 1. The reinforcing frame 14 is located behind the telescopic sleeve rod 8, and the reinforcing frame 14 and the bidirectional lead screw 11 are cross-distributed. A towing ear seat 15 for connecting the towing rope is provided in the middle of the reinforcing frame 14. The provided reinforcing frame 14 can effectively improve the overall strength of the moving frame 1, and the cross-distribution with the bidirectional lead screw 11 will not block the normal rotation of the bidirectional lead screw 11 by the staff. During use, the staff can connect the towing rope through the towing ear seat 15, thereby facilitating the staff to tow the device to move in the pipeline.

[0029] The above has described in detail an embodiment of the present invention, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
